# Taz: a voice-reactive pocket pet

A physical pet reacts with pixel animations as its owner speaks.

## Hardware
Lonely Binary ESP32-S3 N16R8; Waveshare 1.5-inch OLED

An ESP32 drives a small OLED face and connects a microphone and speaker so a physical pet can listen and react with animations.

## Shopping list

Parts for one build. Reuse equipment you already own. Quantities are planning quantities unless the creator explicitly specifies a count; kit contents are not additional purchases.

Quantities are for one build. Unless marked source-specified, they are planning quantities; confirm kit contents and the chosen configuration before ordering.

### Confirm before buying
- Display driver/revision, amplifier suffix, board revision, pin map and power rating remain unresolved. This is not yet a purchase-complete kit.

## How the agent helped
The creator credits Codex with implementing Wi-Fi setup and troubleshooting the firmware's connectivity, audio and conversational behavior. Task execution is an ambition, not a demonstrated feature.

## Before you build
Wired prototype with separate microphone, amplifier and speaker. Performing tasks is future work, not demonstrated functionality.
